BACKGROUND

With the emergence of smart phones in recent years, the demand forminiature camera lens is increasing day by day, and as the progress ofthe semiconductor manufacturing technology makes the pixel size of thephotosensitive devices become smaller, plus the current developmenttrend of electronic products towards better functions and thinner andsmaller dimensions, miniature camera lens with good imaging qualitytherefore have become a mainstream in the market.

In order to obtain better imaging quality, the lens that istraditionally equipped in mobile phone cameras adopts a three-piece,four-piece, or five-piece lens structure. Also, with the development oftechnology and the increase of the diverse demands of users, and as thepixel area of photosensitive devices is becoming smaller and smaller andthe requirement of a system on the imaging quality is improvingconstantly, although the five-piece lens already has good opticalperformance, its focal power, lens spacing and lens shape are stillunreasonable, resulting in the lens structure still cannot meet thedesign requirements of a wide-angle and small height while having goodoptical performance.

Therefore, it is necessary to provide a camera optical lens that hasbetter optical performance and also meets design requirements of awide-angle, small height and ultra-thin.
